Almost great...
Others have mentioned the screen shifting problems + some work that needs to be done in the UI. I assume Mindmeister arent using their own App for daily work...
Theres some functionality missing from the Web browser version - eg Meisertask integration.
Thing is this would be an absolutely killer App on the iPad Pro 12.9 due to the screen real estate if they did some functionality + stability updates. In fact, one of the reasons Im holding off getting the bigger iPad is I need strong Mindmeister capabilities... Actually thinking of looking / swapping to another mindmapping solution so I can get the iPad!
